1982 300 inline 6 in a 1984 f150 long bed. Bored .020 over (first rebuild), not stock pistons, efi manifolds, edelbrock 500cfm 1403 carb, duraspark 2(vacuum advance) distributor, stock rockers, 268H comp cam kit, fully ported NON EFI head, ported combustion chamber, cheap plugs and wires(will be changed), 50,000 volt coil, two homemade exhaust pipes coming into one 21/4inch pipe.. being honest. My goal is to get 17mpg WITHOUT OVERHEATING and a constant 280ish horsepower(in my dreams) truck is pretty stock and stripped, weighs +/4000 lbs wet with 4 speed and granny low, and turns 2,000 rpm in 4th at 65mph.
